Hello All, 

We have a property in a DataType with a edit validate to check if the input value is a date, also the date must be greater or equal of Today. This DataType is delegated.

Before upgrade(Pega 8.2), the validation displayed the error when the user selected a wrong date. See "error-message-before-upgrade" image for reference. 

Post upgrade(Pega 8.6) the validation is still there, it is executed and it is displayed in the tracert, but it is not displayed to user anymore. See "error-message-post-upgrade" image for reference. 

Anybody knows if we have to configure anything else in this new version to display the error message to the user again?

Thanks!
